As a general rule, Polyurethane compounds are moisture sensitive and will react with moisture in the air or with moisture in the substrate they come in contact with during cure. Epoxies are less prone to moisture pick up during cure. Some hardener components however are moisture sensitive and require care in storage and handling. Epoxies tend to be better performers outdoors while urethanes have much better abrasion resistance and elongation properties. Aliphatic type polyurethanes are excellent performers outdoors due to their UV resistance.

Epoxy advantages are physical strength, high temperature resistance and excellent adhesion to most substrates.  Polyurethane advantages are low temperature performance, low exotherm and faster cure speeds. Therefore can be opened to traffic much earlier than epoxies.

Polyurethanes also posses "elastomeric memory" which means that they can withstand considerable deflection (in tension or compression) without permanent deformation. The abrasion resistance of Urethanes is far superior to Epoxies.

Polyurethanes have a much wider hardness range from 5 Shore A up to 85 Shore D, whereas the useful hardness range for epoxies would be from 40D to 90D. Urethanes tend to be less brittle and have higher tensile elongation than other materials with similar hardness.

The advantages of Polyurethanes over Epoxies:

The paints are resistant to most of the chemicalsand are completely impermeable to liquids for long service life, hygiene, and ease of cleaning

PURKAY 066 and 076 top coat paints are designed to be used as protective coat for PU or Epoxy based flooring systems. Due to their very high resistance to abrasion, they guarantee a long service life.

P?RKAY  Self-Levelling materials offer a high quality and cost- effective flooring solution when used in conjunction with a surface primer such as porfil^? BASIC. These coatings have the aabeylity to help distribute surface loads evenly on to the concrete, preventing breaking and cracking.  

Self-Levelling coatings can be applied immediatly after porfil^? BASIC without any further surface preparation. 

porfil^?  is a unique product  used for increasing the mechanical parameters of concrete surfaces. porfil^?   is the ideal primer for further coatings, it fills and condenses all the pores inside concrete, protects from the water which results in increasing the floors maintenance life.  porfil^?BASIC  is used as a concrete primer prior to the application of synthetic flor coatings such as Polyurethane or Epoxy based Self-Levelling coatings.The material is completely resistant to negative water pressure and can be applied at temperature as low as  8?C.Due to its perfect sealing characteristics, adhesion and cohesion problems of the surface coating, which can be a common problem with porous primer, simply do not occure.

PURKAY is a turkish producer of synthetic self-levelling floorings
